Function : Multiple Switch Detection Interface / 32-PIN SOICW EP
Maker : Freescale Semiconductor
The 33975 Multiple Switch Detection Interface with Suppressed Wake up is designed to detect the closing and opening of up to 22 switch contacts. The switch status, either open or closed, is transferred to the microprocessor unit (MCU) through a serial peripheral interface (SPI).
The device also features a 22-to-1 analog multiplexer for reading inputs as analog.
